To '1U whom, it muy comic/'n Be it known that I, WILLIAM A. Hnnxixo, a citizen of the United States, residingr m Philadelphia, in the county of Philadelphia and State ot Pennsylvania, have invented certain new and useful Improvements in Type-ll'riting Machines, of which the following is a specilication.

This invention relates to gross line-spacing mechanisms for typewriting machines, to facilitate the' feeding of paper around the platen for a great distance to a predetermined point by ay single operation.

It is often necessary to insert into the machine bills or other work sheets having wide headings, or to leave a wide margin at the upper ends or" the work, sheets. To advance some bills or sheets to the paper printing point, the operator has to turn the platen through perhaps a complete revolution or more, either by repeatedly operating-the usual line space lever, or by turning the usual finger knobs on the platen axle. Either method necessitates the attention of the operator to prevent overrunning the desired point. on the paper, and requires undue ezipenditure of time and labor.

The main object of this invention is to improve and simplify gross line-spacing meclr anisms, whereby to enable the platen to be turned through more than one revolution at one operation ot a handle; the throw of the platen also beingfcapable of regulation for distances less than one eompiete revolution.

In carrying out this invention, a handle or rotator', having a dog to engage the ratchet connected to the platen, lies normally against a fixed stop. The length of the linespacingT stroke of the platen is determined by an adjustable stop. To increase the range of movement and eiiect a rotation of the platen equal to or greater than one complete rotation. at one stroke of the handle, said adjustable stop is mounted for engagement with a circular rack which is usually fixed, but may at will be made movable about the platen axis, together with one or both of said stops. lt is usually held fixed by means of a bolt, which may be withdrawn to release the rack and enable it to turn about the platen axle, such rotation being suitablylimited. Thus, the stroke of the 'handle or driver is considerably lengthened, and the rotation of the platen correspondingly in# creased. I

The herein described stop mechanism is also adapted for use with condensed billing" machines, in which the platen remains connected tothe crank during both backward and forward strokes of the latter. In the accompanying drawings. Figure l 1s a perspective view, partly broken away, showing the invention applied to the platen frame of an Underwood writing machine. Fig. 2 is a. detail perspective view of the parts disassembled. Fig. 3 is an edge view of the invention, partly in section, showing the means to lock the rack stationary. ,Fi i is a side view, showing` the rack held stationary, and the driver arrested on its initial stroke by the adjustable stop. Fig. 5 is a similar view, showing the driver arrested on its return stroke, by the Xed stop. Fig. 6 is a side view. partly broken away, showing the rack released' to rotate on the axle. the driver being partway on its initial stroke prior to completing one revolution. Fig. i is a side view, showing the position of the part-s at the completion of the initial stroke of the driver, after having made one complete revolution, the rack having been arrested by the engagement of the bolt with the rear face ot the abutment. Fig. 8 is a similar view, showing the positions of the parts at the arrest .of the driver on its return stroke, the platen having `been turned through more vthan one revolution, to advance the paper, and showing; the rack arrested at its opposite limit of movement by the engagement of the bolt. with the abutment. Fig. 9 is a plan, ,showing the platen equipped with the usual line space mechanism and the improved gross line-spacing mechanism. f

The usual platen l of an Underwood w'ritingF machine, is rotatably mounted by an axle 2 in the ends 3 oia platen framenthe ends of the axle projecting: past the ends of the platen frame and having linger wheels4 4 thereon' by which the platen may be rotated forwardly or backwardly to an unlimited extent. The platen may also be rotated forwardly by the usual line-spacing mechanism comprising a line-spacinglever la to operate a slide Za having a pawl 3a, which enla be otherwise effected and the location of the Y clusion oi the ret-urn str oke of lever 9,- as common'ly done-in the line-byline platenf the stop-carrierrecords, for example, in which the roll com- ,handle, stops on said carrier to arrest the nation with a platen, of a driver' comprising Loaders ture, another nearly complete rotation or" the platen is obtainable, whereby to aecommodate a wide range of headings.

The invention is also useful in feeding paper from rolls through the machine, as car prises a number of paper sections or sheets separably connected, each sheet receiving a predetermined line or lines of printing, after which the web is fed forwardly to bring the printing point of the next sheet to the printing line.

The service performed by the bolt 20 as a stop to arrest the turning of the rack may bolt on the disk 15 is not essential to the operation of the invention.

Any suitable pawl may be employed between the lever 9 and the ratchet 5; andv either with or without the usual or known means for withdrawing the pa'wl at the confeeding mechanisms of typewriting machines.

Variations may be resorted to within the so'ope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, I claim: i
